5-second cinematic prehistoric underwater horror video. The enormous mosasaurus slowly glides forward through the dark prehistoric ocean, approaching the camera with powerful, deliberate movements of its tail. Its massive body moves naturally through the water, while its four flippers make subtle adjustments to steer. Its jaws remain partially open, revealing rows of long, jagged teeth. As it draws closer, it slowly opens its mouth a little wider and fixes the camera with its predatory eye. Tiny bubbles escape around its jaws and drift upward. Small fish scatter away from its approaching head, while distant ammonites and marine life move naturally through the dark water. Sunbeams shimmer through the rippling surface far above, illuminating the mosasaurus's wet, rugged scales and dorsal ridges. Suspended particles drift through the water, and faint underwater currents disturb the surrounding haze. The camera slowly retreats as the mosasaurus advances, preserving the creature's enormous scale and keeping its head and open jaws prominent in the frame. Preserve the original mosasaurus design, anatomy, proportions, underwater environment, lighting, and composition. Heavy, realistic aquatic movement with convincing water resistance and momentum. Sound: deep muffled underwater rumbling, subtle bubbles, distant aquatic calls, and a low, ominous animal growl. No music. No soundtrack. No cuts. No sudden attack. No exaggerated movement. No anatomical changes or morphing.
